Note 1) When indoor unit is located at higher level than outdoor unit, allowable height difference is 110m, (If the height difference is over
40m, contact your local dealer for more information . ) but when the indoor unit is located at lower level than outdoor unit, allowable
height difference is 110m (If the height difference is over 50m, need to decide whether to install PDM kit or not . )

Note 3) For indoor units to which no MCU is connected, be sure to set their options to "Cooling only indoor unit, " and then connect them to a
low pressure gas pipe and a liquid pipe . Be sure to combine the cooling only indoor units so that their total capacity becomes 50% or
less of the total capacity of all indoor units .
Note 4) In case of connecting more than one indoor unit in one MCU Port, the below indoor units cannot be combined . ERV plus
